The U.S. ambassador to Brazil has met with his Brazilian counterpart following revelations that the National Security Agency's spy program directly targeted the South American nation's leader.

U.S. Ambassador Thomas Shannon arrived and left Brazil's Foreign Ministry Monday without speaking to reporters. There was no comment from Brazil's Foreign Ministry either.

But lawmakers in Latin America's largest nation expressed outrage after the report on Globo TV network cited documents from NSA leaker Edward Snowden. They're calling for a wide-ranging investigation into the program.

The report says the U.S. was targeting President Dilma Rousseff's emails and telephone calls with her top aides. The documents don't include excerpts of intercepted messages.

But U.S. journalist Glenn Greenwald has the trove of Snowden documents and says it's clear that Rousseff's messages were being read.
